TREATMENT-STOOL.

Specification of Letters Patent.

Patented Jan. 6, 1920.

Application filed March 7, 1917. Serial No. 153,146.

To all whom it may concern:

Be it known that I, J OHN V. MOMANIS, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Treatment- Stools, of which the following is a specification.

My invention relates to improvements in treatment stools for use of Osteopaths and other drugless healers. One of its objects is to provide a stool having an adjustable seat for the patient, a foot rest for the patient, and a foot rest for the operator, arranged so that the operator may secure a rest at varying heights from the. floor for his feet, and thus place himself in position to flex different portions of the spinal column of a patient. Another object is to provide a stool in which the seat is adjustable both vertically and to different positions of inclination. Another object is to provide a stool having an adjustable foot rest for the operator and convenient means to lock and release the adjustable foot rest. Another object is to provide simple and readily portable apparatus by means of which any desired section of the spinal column may be flexed. My invention also comprises certain details of form combination and arrangement, all of which will be fully set forth in the description of the accompanying drawings in which;

Figure 1 is a side elevation of one form of myimproved apparatus in position for use.

Fig. A is a side elevation illustrating a modification.

Fig. 5 is a plan view of the operators foot rest of Fig. 1 detached.

Fig. 6 is a detail of the seat inclining and adjusting mechanism.

The accompanying drawings illustrate the preferred embodiments of my invention.

As illustrated in Figs. 1, 2 andB, A repre-' sents the base.

B represents a standard, preferably of rectangular cross section seated in a corresponding vertical recess 1n the base A, and adjustable as to height relative to the base, and locked to its adjusted position preferably by means of a hand wheel 2 threaded to the base, and a series of recesses 3 in the standard B to receive the end of the threaded shank of the hand wheel. At the upper end of the'standard B is a head 4 having a pair of ears 5 atone side and a pair of ears 6 at the other side. A seat D preferably upholstered is provided on its under side with a pair of ears 7 pivotally connected to the ears 5 of the head 4. The seat D has also pivotally connected to its under side a pair of short links 8 which at their opposite ends engage eccentrics 10 carried by a square shaft 9 and with hubs 10 journaled in the ears 6 ofhead 4. A hand lever 12 enables the shaft 9 and eccentrics 10 tobe rotated against a friction brake or looking member 14 to adjust the seat to various positions of inclination relative to a normal horizontal position, either toward the front or rear. The rectangular shank of standard B prevents the seat rotating thereon relative to base A.

The base carries a U-shaped foot rest 15 for the feet of the patient to rest upon and secure for the patient a firm position upon the seat D. The base A has a rearwardly projecting bracket 16 which at its rear end has a pair of forked arms 17 provided with ears 18. A yoke shaped foot rest 22 for the operator is pivotally connected to the base at 19, and projects rearwardly, being provided with one or more pairs of foot rests or stirrups 20 to receive the toes of the feet of the operator. Links 21 are connected at one end to the foot rest 22 and at the opposite end to the upper end of a rectangular bar 2% which slides vertically between the forked arms17. A locking member 25 having a rectangular recess therein for the passage of the bar 2a,. is pivotally connected to the ears 18, so that actuated by gravity it will tend to assume an inclined position and bind upon the bar 24 where it passes through the rectangular recessv in the locking member 25, and which is at one side of the pivotal point 18, thereby serving to lock the bar 24 automatically against movement clownwardly, but leaving. it free to move upwardly. An actuating lever or projection 26 on member 25 enables the operator .to

lift the member 25 with the toeof one foot and thus release the lockingefi'ect on bar 24, while by means of his other foot. in one ofpthe stirrups, the foot rest 22 may be lowered to any desired extent. The operator is thus enabled to conveniently adjust the foot rests 22 either upwardly or down v thereof.

wardly, using his feet for that purpose, and to have the foot rest automatically locked to its adjusted position. By employing one or more sets of stirrups 20 on the foot rest lever, a wide range of positions vertically for the feet of the operator is attainable.

Strap-loops 3 1 are preferably attached to seat D to enable one or more straps to be employed if desired to assist in retaining seated upon a table For other object of greater elevation than the seat D, and with his feet in one pair of stirrups, and by adjusting the stirrups vertically relative to the seat D is enabled to rest his knees as'a support or leverage against different portions of the spinal column of the patient, and by placing his hands on the shoulders or'other upper portions of the patient to articulate and exerclse any desired section or sections of the patients spine.

In the modification shown in Figs. 4 and 5 I have illustrated a bar 30 adjustably and pivotally secured at 32 by means of a hand locking wheel 33 to the outer end of bracket 16, similar to bracket 16 of Fig. 1. The bar 30 carries a series of horizontal cross-bars 31 each of which may serve as a support for the feet of the operator and enable him to secure a high or low support for his feet by changingthem from one rod 31 to another. The pivotal adjustment of bar 30 enables the same .to be adjusted to different positions of inclination upon the center 32. to secure the desired relation of the bar 30 and rods 31 relative to the stool, and when using the lower'rods 31 to avoid contact of the upper portion of bar 30 or rods 31 with the legs of the operator.

Fig. 6 illustrates partly in section aneccentric shaft and its connections, constitut- 7 ing the preferred form of mechanism for securing a horizontal or inclined position of the seat in either Fig. 1 or Fig. 4.

The mechanism herein illustrated and de scribed is capable of considerable modification without departing from the principle of my invention.

Having described my inventiorn what I claim is:

1. A treatment stool comprising a base, a vertically adjustable standard mounted upon said base to non-rotatably support a seat, a backless patients seat mounted upon The operator takes a position said standard and tilta'ble fore-and-aft relative thereto to different positions of inclination, and means carried by and at the rear of the stool to support the feet of an operator, the foot-engaging parts thereof lying in a plane above the base and below the seat toenable the operator to bring his knees to bear against the back of the patient.
